A great concept! This feels like the tutorial before the actual game with harder puzzle maps that I'd love to play. The black and white, textureless, cube-like style made me feel like playing a prototype at the beginning, but now I think it could also totally stay this way. I read comments about the camera/perspective, but I'd say I like it how it is; you could even think about using it as a mechanic and add optical illusions with this isometric style. Enjoyed it :)
